How to call RScript function in an extension

[Anonymous]

Looking for advise on how to call an RScript in an extension backend. I have configured R with Qlik Sense and the script gets called successfully from front end.

Extension Functionality - When user clicks on a button, the extension should dynamically create an QHypercube (internally call R Function) and display its output.

Below is my code

controller: ['$scope', function ( $scope ) {

var app = qlik.currApp();

$scope.checkIfButtonPressed = function($event){

          app.createCube({

               qDimensions:[],

                   qMeasures:[{

                         qDef:{

                           qDef:"R.ScriptAggr('count(q$survived);',survived)"   //-- this doesnt give any output

                         //qDef: "count(survived)"   --this works

                         }

                    }],

                    qInitialDataFetch:[{

                         qHeight:20,

                         qWidth:2

                    }]

                    },function(reply){

                         alert(reply.qHyperCube.qDataPages[0].qMatrix[0].qNum);

                    }

               });

     }

}

I figured it. Calling R from hypercube works, I was using count() function which has to be len() in R. I could see data being sent to RServe and the communication happening. Thanks
